FINE NO LONGER BEING MADE. Schmidt® is now making refills in all styles under the label of Private Reserve Ink®. These are their exact refills, just with the Private Reserve Ink® label on them rather than Schmidt®. Please note that the quality of the refill is the same as the OEM.

The BLACK EXTENDER on the refill is part of the PEN and is NOT part of the refill....KEEP THIS EXTENDER.
